yes i know , but that is for only one user , i need the modifications for 32 user that’s what confuses me

[BoykaParticipant]

i installed the programe on another computer and baaam , the above files worked with no error

now ,

i just need for the 32 user , the following values for both the ofdm modulator and demodulator :

1- the number of subcarriers
2- the position array
3- the number of fft
4- the number of cyclic prefix points

can you give me the appropriate values of those 4 variables ??

i will be very appreciated

thanks in advance

[BoykaParticipant]

i installed the program on another computer and the files worked now lucky

[BoykaParticipant]

the 3rd party licence is colored with red not blue as your version , that may be the problem

[BoykaParticipant]

thank you very much sir , the file didn’t open and give me the same message i told you before , now i’m completely sure there is something wrong with my version

[BoykaParticipant]

ok sir thank you

[BoykaParticipant]

i will sir , but before that , can we give it a try , can you sir save the file by your program and upload it here again , i think it may solve the problem

[BoykaParticipant]

i have been trying for two days to find the problem with my design , i tried to increase the power , decreasing the fiber length , using optical and electrical gain , changing the position array as user defined or let it automatic .

but nothing of all that solved the problem

i don’t know what to do next ?

that’s very helpful thank you alistu,

well i’m trying to open the file attached that i found on the site , but it says failed to load document from storage

despite that i’m having the latest version of optisystem , what is the problem then ??

hello alistu ,

thank you very much , so according to my understand ,in optisystem 13 i can connect the ofdm modulator and demodulator without defining the position arrays ?

another thing , can you please take a look at my design that i attached above , is this topology correct or i’m missing something here
